Treatment of quinolines and isoquinolines with benzoyl peroxide in tertiary amides, such as N,N-dimethylacetamide, N,N-dimethylpropionamide, and N-acetylpyrrolidine, etc., under irradiation with a Hg lamp in the temperature range of 35 °C to 40 °C gave C-C-bonded quinolines and isoquinolines bearing amide groups with high regioselectivity in good to moderate yields, respectively, under transition-metal-free conditions.

A novel method to synthesize 2-azaaryl tetrahydroquinolines by the base-promoted tandem reaction of azaaryl methyl amines and styrene derivatives is reported (over 30 examples, yields up to 95%). Mechanistic probe experiments demonstrate that the deprotonation of the benzylic C-H bond and the addition to the styrene vinyl group proceeds via the SNAr mechanism.

The synthesis and biological evaluation of a series of novel 1-(aryloxy)-2-propanolamines and several related deshydroxy analogues are described.Compounds 4-29 were prepared and investigated for their class III electrophysiological activity in isolated canine Purkinje fibers and in anesthetized open-chest dogs.None of these compounds showed any class I activity.On the basis of the in vitro data, structure-activity relationships for the series are discussed.Two compounds, N-propoxy>phenyl>methanesulfonamide (12, WAY-123,223) and N-phenoxy>propyl>amino>methyl>-6-quinolinyl>methanesulfonamide (24, WAY-125,971) were identified and characterized as potent and specific class III antiarrhythmic agents in vitro and in vivo.Compound 12 was found to be orally bioavailable, to produce large increases of ventricular fibrillation threshold (VFT), and, in some instances, to restore sinus rhythm from ventricular fibrillation in anesthetized open-chest dogs at a dose of 5 mg/kg (iv).The enantiomers of 12 (i.e., 13 and 14) were synthesized and were found to exhibit similar electrophysiological effects in the Purkinje fiber screen.Compound 24, a propylamine analogue with potency and efficacy comparable to those of UK-68798 (2) and E-4031 (3), was studied in voltage-clamp experiments (isolated cat myocytes) and was found to be a potent and specific blocker of the delayed rectifier potassium current (IK).
